Does anybody know what the little dots on the home screen above the apps are, sometimes three sometimes four, just out of interest

Hi there...those little dots are the number of pages you have currently available to fill with apps. When you do the 4-finger swipe, you will see the next dot light up to show the page you are on. Go all the way to the left and you will hit the Search area...hence the magnify glass icon.

You have posted in the Poll Section, which will not give you as good attention as you would like. I am moving this to General Discussions.

Thanks!

Cricky that was quick.so positive when it works like that

Glad that helped you!
